Swift Testing Code Review

What it does

This skill assists with reviewing Swift code, specifically focusing on testing practices for frontend UI and user experience development. It provides guidance and references related to common testing patterns like #expect vs #require, parameterized tests, async sequences, and test organization using @Suite. The tool helps ensure adherence to best practices in Swift testing, improving code quality and reliability.

When to use it

• When reviewing code that utilizes the #expect or #require macros for assertions.
• During reviews of tests employing arguments or traits within @Test functions.
• When assessing asynchronous testing approaches involving confirmation and completion handlers.
• For evaluating the organization of test suites using @Suite and related features.

Key capabilities

• Provides references to documentation on #expect vs #require, expression capture, and error testing (references/expect-macro.md).
• Offers guidance on parameterized tests with arguments and traits (references/parameterized.md).
• Covers best practices for asynchronous sequences and completion handlers (references/async-testing.md).
• Details test organization using @Suite, tags, parallel execution, and serialization (references/organization.md).
• Includes a checklist of common review points related to Swift testing conventions.

Example prompts

• "Review this code snippet for proper use of #expect and #require."
• "Check if these parameterized tests are using zip() correctly."
• "Assess the organization of this test suite, paying attention to .serialized usage."

Tips & gotchas

• The skill focuses specifically on Swift testing practices; it is not a general code review tool.
• Pay close attention to the checklist provided for common pitfalls in Swift testing.
• Reviewing completion handlers should use withCheckedContinuation, not confirmation.
